| 摘 要： | 污水在管道输送的过程中很容易出现厌氧环境，产生的硫化氢常引起恶臭、中毒和腐蚀等一系列问题。这些问题可归结为因硫元素在管道中不同相态间的迁移转化所致，该过程主要包括三个阶段：污水中硫化物的产生和扩散、硫化氢由液相到气相的逸散以及管壁上硫化氢的氧化进而引起混凝土等管道腐蚀。对这三阶段机理模型进行了归纳总结，最后在三阶段模型的基础上阐述了控制和预防硫化氢问题的方法，从而为污水输送系统的运行、管理和设计提供参考。

| Abstract: | The anaerobic environment usually appears in sewer networks,and results in the emission of hydrogen sulfide,which usually contributes to odor,toxicity and corrosion problems.The hydrogen sulfide problems are attributed to the transference and transportation of the element sulfur in sewers:sulfide generation and diffusion in liquid phase,hydrogen sulfide emission from liquid to gaseous phase,and hydrogen sulfide oxidation on pipe wall and induced pipeline corrosion.The three-stage mechanism models are summar... |
